Chapter 1

Getting Started with LaTeX

LaTeX is a document preparation system renowned for its ability to produce technically detailed and beautifully typeset documents that are publication-ready. This chapter provides a foundational understanding of LaTeX, from installation across different operating systems to creating your first document. It carefully guides readers through the basic structure of a LaTeX file, essential text formatting techniques, the inclusion of external packages, and the fundamental aspects of math typesetting. By the end of this chapter, readers will have compiled their first document and begun to navigate the common errors and troubleshooting practices inherent in the learning process.

1.1

Introduction to LaTeX and Its Benefits

LaTeX, pronounced ’Lay-tech’ or ’Lah-tech’, is a high-quality typesetting system; it includes features designed for the production of technical and scientific documentation. LaTeX is widely used for medium-to-large technical or scientific documents but it can be used for almost any form of publishing.

LaTeX is not a word processor. Instead, it is a document markup language. The author uses plain text as opposed to formatted text, as in WYSIWYG word processors like Microsoft Word, LibreOffice Writer, or Apple Pages. LaTeX uses the TeX typesetting program for formatting its output, and is itself a collection of macros for TeX.

One significant benefit of LaTeX is its ability to handle complex typesetting tasks like mathematical equations, references, and bibliographies with ease. This is one reason why LaTeX is extensively used in academia and research, where such tasks are common. LaTeX also allows for high customization and precision in document creation, making it possible to achieve exactly the desired layout and appearance.

Another advantage of LaTeX is the quality of the typeset documents it produces. The algorithms used for formatting text and mathematical expressions in LaTeX are highly sophisticated, ensuring that both the on-screen and printed output look highly professional. This is particularly important for scientific publications, theses, and dissertations, where the clarity of the presentation can complement the quality of the content.

LaTeX also excels in managing cross-references, bibliographies, indexes, and citations. Features that can be cumbersome to manage in traditional word processors are often much simpler in LaTeX. For example, LaTeX automates the numbering of sections, figures, and tables, updating references throughout the document if the order is changed. This makes document revision more straightforward, reducing the risk of inconsistencies and errors.

Moreover, LaTeX offers unparalleled support for typesetting complex mathematical formulas and notations. Mathematical equations are rendered clearly and beautifully, adhering to the conventions of mathematical typesetting. This feature alone makes LaTeX indispensable to many in the fields of mathematics, physics, engineering, and beyond.

Another of LaTeX’s strengths is its portability. LaTeX files are plain text, meaning they can be created and edited with any text editor. They can be compiled into a finished document on almost any operating system, ensuring that documents can be worked on across different platforms without compatibility issues.

Finally, LaTeX is open source and freely available. There is a large and active community around LaTeX, offering extensive documentation, user guides, and forums for troubleshooting. This makes it relatively easy for newcomers to find help and resources as they begin to work with LaTeX.

In essence, LaTeX facilitates a write once, typeset anywhere approach, freeing the author to concentrate on content while leaving the formatting to LaTeX. This separation of content and style is a hallmark of professional typesetting and publishing, marking LaTeX apart from standard word processing software for producing complex and nuanced documents.

1.2

Installing LaTeX on Various Operating Systems

Installing LaTeX is a prerequisite for creating documents using its typesetting system. This section outlines the process of installing LaTeX on three major operating systems: Windows, macOS, and Linux. Each platform requires a slightly different installation approach due to the differences in the operating systems’ architecture and file management systems.

Windows: For Windows users, the recommended LaTeX distribution is MiKTeX. It is a comprehensive distribution that includes all the necessary tools for LaTeX document production. To install MiKTeX, follow these steps:

1. Visit the official MiKTeX website ( https://miktex.org) and navigate to the download section. 2. Select the version suitable for your architecture (32-bit or 64-bit). 3. Download the installer and run it. During the installation, you can choose whether to install for all users or just for yourself. It is recommended to select the option to install missing packages automatically. 4. Once the installation is complete, verify the installation by opening the MiKTeX Console application.

macOS: For macOS, TeX Live is the recommended distribution, and it includes a convenient package called MacTeX. This package contains everything you need to get started with LaTeX on macOS. To install MacTeX, follow these instructions:

1. Go to the MacTeX homepage ( http://tug.org/mactex/). 2. Download the MacTeX.pkg file. 3. Open the downloaded file and follow the instructions on the screen. The installer will take care of the rest. 4. To verify that the installation was successful, open the Terminal and type latex. This should return a prompt indicating that LaTeX is ready to process documents.

Linux: The procedure for installing LaTeX on Linux depends on the distribution you are using. However, TeX Live is generally the recommended installation for most Linux distributions. For Ubuntu and other Debian-based distributions, you can install TeX Live using the following commands in the terminal:

1

sudo

apt

-

get

update

2

sudo

apt

-

get

install

texlive

-

full

For Fedora, Red Hat, and other RPM-based distributions, use:

1

sudo

dnf

install

texlive

-

scheme

-

full

texlive-full and texlive-scheme-full are comprehensive packages that include all TeX Live components. Note that these commands will install a large set of packages, requiring significant disk space and download time. It is a comprehensive installation that ensures you have all the necessary packages and fonts for LaTeX document creation.

Once LaTeX is installed on your system, you can begin creating and compiling LaTeX documents. Remember to regularly update your LaTeX distribution to get the latest package updates and improvements.

1.3

Your First LaTeX Document

Let’s embark on the creation of your first LaTeX document. This exercise aims to introduce you to the basic syntax of LaTeX and how a minimal but complete document is structured. By the end of this section, you will have created a simple document that contains text formatted in different styles.

To begin, open your LaTeX editor and create a new file with a ‘.tex‘ extension. This extension denotes a file written in LaTeX. Insert the following code into your newly created file:

1

\

documentclass

{

article

}

2

3

\

begin

{

document

}

4

5

Hello

,

world

!

6

7

\

end

{

document

}

The ‘\documentclass{article}‘ line at the beginning specifies the type of document you are creating. In this case, it’s an article. LaTeX supports various document classes, each tailored for different types of documents, including reports, books, and letters.

Following the document class declaration, the ‘\begin{document}‘ and ‘\end{document}‘ lines encapsulate the contents of your document. Everything you wish to include in your document, from text to images and tables, must be placed between these two commands.

Within these commands, the phrase ‘Hello, world¡ is the content of your document. In LaTeX, plain text can be directly typed into the document.

After saving your file, it’s time to compile it into a PDF. This process translates your ‘.tex‘ file into a document viewable on PDF readers. To compile your document, use your LaTeX editor’s compile button, or if you are using a command-line interface, navigate to your file’s directory and run the following command:

1

pdflatex

yourfilename

.

tex

Replace ‘yourfilename‘ with the name of your LaTeX file. After running this command, LaTeX generates several files along with a PDF version of your document. Open this PDF to view your first LaTeX document, which should display the phrase ‘Hello, world¡ on it.

To further familiarize yourself with basic text formatting, add the following lines to your document, between the ‘\begin{document}‘ and ‘\end{document}‘ commands:

1

This

is

\

textbf

{

bold

}

text

,

this

is

\

textit

{

italicized

}

text

,

and

this

is

\

underline

{

underlined

}

text

.

This is bold text, this is italicized text, and this is underlined text.

After adding these lines, recompile your document. The PDF should now include a sentence that demonstrates bold, italicized, and underlined text. These commands—‘\textbf{}‘, ‘\textit{}‘, and ‘\underline{}‘—are fundamental text formatting tools in LaTeX, allowing you to emphasize different parts of your text as needed.

Through these steps, you’ve created your first LaTeX document and begun to explore text formatting. This foundation will be expanded in the following sections, where you will learn about more advanced formatting options, how to structure your documents into sections, and how to include mathematical equations and external packages.

1.4

Understanding the Structure of a LaTeX File

To grasp the full potential of LaTeX, one must first become familiar with the foundational structure of a LaTeX file. This structure is pivotal not only for the compilation process but also for maintaining the organization and readability of your document. A LaTeX file, typically with the extension ‘.tex‘, is a plain text file that includes both the content of your document and the commands that tell LaTeX how to format the content.

A basic LaTeX document consists of two main parts: the preamble and the document body.

The Preamble

The preamble is located at the beginning of the file and contains global settings and commands that affect the entire document. It is where you define the type of document you are creating, load necessary packages, and set up configurations like margins, header/footer styles, and hyperlink settings. The preamble begins with the \documentclass command.

1

\

documentclass

[12

pt

,

letterpaper

]{

article

}

In this example, the \documentclass command specifies that we are creating an article with a font size of 12 points and letter-size paper. Options and document classes can vary depending on the type of document you are producing.

Following the \documentclass command, you can load external packages with the \usepackage command. Packages extend the capabilities of LaTeX. For instance, to enhance mathematical typesetting or to incorporate images, you might use:

1

\

usepackage

{

amsmath

}

2

\

usepackage

{

graphicx

}

These commands instruct LaTeX to incorporate functionalities from the ‘amsmath‘ and ‘graphicx‘ packages.

The Document Body

The document body starts with the \begin{document} command and ends with the \end{document} command. It is within this portion of the LaTeX file that you will write the actual content of your document, including text, figures, tables, equations, etc.

1

\

begin

{

document

}

2

Hello

,

World

!

3

\

end

{

document

}

This simple example demonstrates the minimal content of a document body, producing a document with the phrase Hello, World!.

Basic Commands for Structuring a Document

Within the document body, sections, subsections, and paragraphs are delineated using LaTeX commands, providing a hierarchical structure to the document. For instance:

1

\

section

{

Section

Title

Here

}

2

\

subsection

*{

Subsection

Title

Here

}

3

\

paragraph

{

Here

is

the

text

for

a

paragraph

.}

This hierarchical organization facilitates navigation throughout the document, especially in longer texts.

Including Mathematics

LaTeX is particularly distinguished for its powerful math typesetting capabilities. You can insert inline mathematical expressions by enclosing them within dollar signs ($):

1

The

famous

equation

$E

=

mc

^2

$

expresses

the

equivalence

of

energy

and

mass

.

For displaying equations in a separate line, you can use the equation environment:

Compiling a LaTeX Document

Compiling a LaTeX document transforms the source ‘.tex‘ file into a finished document in PDF format. This process involves running LaTeX commands, which interpret the markup in the ‘.tex‘ file and output a formatted document. For example, using the ‘pdflatex‘ command:

pdflatex mydocument.tex

This command produces ‘mydocument.pdf‘, converting the LaTeX markup into a PDF document.

Understanding the structure of a LaTeX file, from the delineation of its preamble to the organization of its body, is crucial for effectively using LaTeX. As you become more familiar with LaTeX commands and environments, you will be able to craft documents of varying complexity, from simple articles to comprehensive books. Achieving proficiency in LaTeX is a matter of practice and experimentation, leveraging the system’s extensive capabilities to fulfill your document preparation needs.

1.5

Basic Text Formatting: Bold, Italics, and Underline

Formatting text in LaTeX involves specific commands that allow one to emphasize certain parts of the content effectively. These formatting options include making text bold, italics, or underlined. This section will discuss the commands associated with each formatting option, providing a clear understanding of how to apply these styles to your document.

To begin with, let’s consider the command for making text bold. In LaTeX, the command is used for this purpose. The syntax is straightforward: any text placed within the curly braces immediately following the command will be rendered in boldface. Here is an example:

1

\

textbf

{

This

text

will

appear

bold

.}

This text will appear bold.

Similarly, to italicize
